Extraordinary security measures are being taken during the federal death penalty trial of accused Boston Marathon bomber Dzhokhar Tsarnaev, one of the most scrutinized U.S. terror cases in years.
White vehicles from Homeland Security line up bumper-to-bumper in front of Boston’s federal courthouse while others periodically circle the block. Boston police officers patrol the perimeter on foot, and a dark special operations van is stationed near the entrance. In the harbor nearby, armed U.S. Coast Guard boats ply the waters, and inside the court building officers with dogs roam the hallways.
